Nozzle assembly for spraying

Abstract

A rotatably operable nozzle assembly for spraying provided to an operating member for spraying which has a valve stem engaging hole into which a valve stem of a mounting cap of an upper end of a canister is engaged, wherein a spray port of the spray port member is opened when the nozzle assembly for spraying is hung, while a horizontal holding plate is positioned to be brought into contact with or approach towards a top face of the spray port member in a position for covering the spray port of the spray port member when the nozzle assembly for spraying is rotated by 90 degrees into a horizontal position; and a base portion of the nozzle assembly for spraying has a face suitable for rotation on the side opposite to the spray port, thereby allowing rotation of the operating member for spraying.

We claim: 
     
       1. A rotatably operable nozzle assembly, for an operating member for spraying which has a valve stem engaging hole into which a valve stem of a mounting cap at an upper end of a cannister is engaged, comprising: a spray port member having a spray port, a holding plate, and a base portion on a side opposite said spray port, said spray port being opened when the nozzle assembly is in a vertical position, and said holding plate is positioned to be contacted with or approached by a top face of said spray port member, so as to cover said spray port when the nozzle is rotated by 90 degrees into a horizontal position; and said base portion of the nozzle assembly has a face suitable for rotation, so as to allow rotation thereof for spraying, on the side opposite said spray port.   
     
     
       2. A rotatably operable nozzle assembly, for an operating member for spraying which has a valve stem engaging hole into which a valve stem of a mounting cap at an upper end of a cannister is engaged, comprising: a spray port member having a spray port, a holding plate, and a base portion on a side opposite said spray port;   an internal cylindrical body, having a tip, forming a passage in said base portion;   a cylindrical portion of said spray portion fitted into said tip of said internal cylindrical body;   said spray port being opening when the nozzle assembly is in a vertical position, and said holding plate is positioned to be contacted with or approached by a top face of said spray port member, so as to cover said spray port when the nozzle is rotated by 90 degrees into a horizontal position; and said base portion of the nozzle assembly has a face suitable for rotation, so as to allow rotation thereof for spraying on the side opposite said spray port.   
     
     
       3. A rotatably operable nozzle assembly, for an operating member for spraying which has a valve stem engaging hole into which a valve stem of a mounting cap at an upper end of a cannister is engaged, comprising: a spray port member having a spray port, a holding plate, and a base portion on a side opposite said spray port, said spray port being opened when the nozzle assembly is in a vertical position, and said holding plate is positioned to be contacted with or approached by a top face of said spray port member, so as to cover said spray port when the nozzle is rotated by 90 degrees into a horizontal position; and said base portion of the nozzle assembly has a face suitable for rotation thereof for spraying on the side opposite said spray port; and   an elastic sealing member facingly contacting said face, so as to allow rotation thereof for spraying.
